Also, it's interesting to see scientific workflows can be
published via Wiki (e.g., myExperiment).

But as far as I know, myExperiment does not allow editing the
actual workflows online, you can only upload and visualize workflow
files that have been created on the client-side. I guess that still
poses a significant hindrance to realizing the 'anyone can edit'
philosophy of classic wikis. In this regard, fully server-sided
systems such as the well known Yahoo Pipes or the quickly maturing
Semantic Web Pipes [1] might be the way to go.

Regarding the article, it will probably seem a bit puzzling to many
people on this mailing list that Lincoln Stein writes

"To my knowledge, there is currently only one project that aims to
bring the pure semantic web to biomedical research. That project is
the Simple Semantic Web Architecture and Protocol (SSWAP30)"

It's nice that Nature allows the community to add descriptions
about our various projects on the wiki page associated with the
article [2]; unfortunately, though, most readers of the original
article will probably not have a look at that wiki.
